Quandles: Introduction and recent developments
Quandles are algebraic structures that play a prominent role in knot theory and also form a class of set-theoretic solutions of the Yang-Baxter equation. After a brief introduction to quandles, I will focus on recent developments and open problems, including the Hayashi conjecture and the isomorphism problem for principal quandles.
